What does Explanation Of Benefits (EOB) mean?

A summary from your insurer of what was billed, what the plan processed, and what you may owe. It is not a bill.

Illustration — not a plan price

Compare the EOB with the provider's bill before paying, and ask about any amount that does not match.

The actual plan document controls. Verify its definitions, network, exclusions, dates, and amounts before relying on the illustration.
